Low-Power Modes  
Overview  
The Z8F640x family products contain power-saving features. The highest level of power  
reduction is provided by Stop mode. The next level of power reduction is provided by the  
Halt mode.  
Stop Mode  
Execution of the eZ8 CPU’s STOP instruction places the Z8F640x family device into Stop  
mode. In Stop mode, the operating characteristics are:  
Primary crystal oscillator is stopped  
System clock is stopped  
eZ8 CPU is stopped  
Program counter (PC) stops incrementing  
Watch-Dog Timer’s internal RC oscillator continues to operate  
If enabled, the Watch-Dog Timer continues to operate  
All other on-chip peripherals are idle  
To minimize current in Stop mode, all GPIO pins that are configured as digital inputs must  
be driven to one of the supply rails (VCC or GND). The Z8F640x family device can be  
brought out of Stop mode using Stop Mode Recovery. For more information on STOP  
Mode Recovery refer to the Reset and Stop Mode Recovery chapter.  
Halt Mode  
Execution of the eZ8 CPU’s HALT instruction places the Z8F640x family device into Halt  
mode. In Halt mode, the operating characteristics are:  
Primary crystal oscillator is enabled and continues to operate  
System clock is enabled and continues to operate  
eZ8 CPU is idle  
Program counter (PC) stops incrementing
